The composition may best be used by applying the same by brush or other convenlent implement to surfaces or articles coated with the paint, varnish or other substance to be removed, and by allowing it to soak into or commingle with said substance, until the same shall become thoroughly impregnated with the detergent and wet, soft or gelatinous, and then to remove such substance by means of a sponge, brush or other convenient implement,moistened with water.

The above described detergent has been found, after careful experiments, to be most effective and useful when made according to the process and in the manner above stated;
